Asbestos

© Business & Legal Reports, Inc What Is Asbestos? Group of natural minerals Still mined in some countries Long, thin, and strong fibrous crystals Resistant to heat and corrosive chemicals “Miracle fiber”

© Business & Legal Reports, Inc Asbestos Facts 6 types 3 most common in products: Chrysotile Amosite Crocidolite

© Business & Legal Reports, Inc Why was it used? Fire and heat resistance Spray-applied fireproofing Heat resistant clothing & gloves/textiles Gaskets, brake pads, etc. Insulation qualities (thermal & acoustic) Pipe, duct, tank insulation Sound board, acoustic panels, acoustic ceiling tiles and sprays

© Business & Legal Reports, Inc Uses cont. Chemical resistance Fume hoods Lab table tops Cement panels/pipes Adds “tensile” strength Flooring materials (tile/sheeting) Plaster/stucco, joint compound

© Business & Legal Reports, Inc Uses cont. Adds durability Roofing materials Flooring materials Paint Asbestos cement panels/pipes Assists in application of other products Any spray-applied product Trowelled-on plasters and adhesives Mudded elbows or junctions on piping or trowelled-on insulation

© Business & Legal Reports, Inc Health Hazard No health risk when asbestos materials are intact Potential inhalation hazard from damaged asbestos materials Airborne fibers are usually microscopic

© Business & Legal Reports, Inc Health effects Most asbestos-related disease results from long-term (often heavy) exposure to asbestos. Common occupations with long-term exposures: fabricators, insulators, construction (carpentry, HVAC, plumbing, bricklaying)

© Business & Legal Reports, Inc Asbestos Regulations Started in 1972, involved phaseout program Included: Ban on many applications of asbestos Regulations on removal, transport and disposal Regulations regarding protection of workers Regulations regarding protection of K-12, public buildings

© Business & Legal Reports, Inc Friable Asbestos Any ACM which can be crumbled, pulverized or reduced to powder by hand pressure. Friable materials: Pipe insulation Insulating boards Insulating textiles

© Business & Legal Reports, Inc Non-friable Asbestos Any ACM which, in its current state, cannot be crumbled, pulverized or reduced to powder by hand pressure. (includes ceiling and floor tiles, caulking) Non-Friable asbestos can become Friable w/: - Water or heat damage - Age or natural deterioration - Mechanical disturbance (sanding/abrading/cutting/grinding, etc.)

© Business & Legal Reports, Inc In-Place Management EPA recommends an in-place management program Removal may create hazards. Repair as needed. Removal is required only during building demolition or renovation Avoiding disturbance is ideal!

© Business & Legal Reports, Inc EPA AHERA Program (Asbestos Hazard Emergency Response Act) Enacted in 1986 to protect K-12 Requires: Asbestos management plan Includes management in place Specific controls and abatement practices Regular inspections Parental notification of any abatement activities and annual notification regarding the availability of the plan

© Business & Legal Reports, Inc NESHAP National Emission Standard for Hazardous Air Pollutants (EPA Rule) Applies to buildings and structures regardless of age of construction. Is triggered for: All building demolitions Any renovation where the following is disturbed: Greater or equal to: 160 sq ft of regulated ACM Greater or equal to: 260 linear ft of regulated pipe insulation

© Business & Legal Reports, Inc NESHAP cont. Requires: Inspection and development of report Notification (10 working days) Work practices Waste management Training

© Business & Legal Reports, Inc Cal-OSHA considerations Asbestos workers: Ensure proper work practices/training/supervision Occupant and non-asbestos contractor safety

© Business & Legal Reports, Inc Location of asbestos on campus Asbestos-containing materials can be found in many campus buildings constructed prior to Sampling of campus buildings for asbestos completed in 1994 and during TII Project.

© Business & Legal Reports, Inc Management of remodeling projects and maintenance EH&S reviews all remodeling/demolition plans Facilities Management Project Managers are provided with training

© Business & Legal Reports, Inc EHS/Fac Mgmt requirements Prior to abatement Arrange for sample collection and analysis as necessary Review lab results to determine which materials contain asbestos Review abatement needs with Certified Asbestos Abatement contractor

© Business & Legal Reports, Inc Responsibilities During abatement Contractors must meet/exceed all EPA and OSHA requirements Work scheduled during off hours whenever possible All work must be under containment Building HVAC system is isolated Room kept under negative pressure All air leaving the room is filtered Limited access

© Business & Legal Reports, Inc Responsibilities During abatement cont. Ensure that: off-hours employees are notified signage & posted material is maintained Containment and negative pressure is maintained

© Business & Legal Reports, Inc Clearance sampling/analysis Air samples are collected by a certified consultant at the end of the abatement work. Air samples are analyzed by an certified laboratory. Clearance is achieved: PCM: analysis that reads all fibers Clearance level: <.01 fibers/cc TEM: analysis that reads only asbestos fibers Clearance level: <70 structures/cc
